Filed May 2, 1955 INVENTOR. ROBERT E. MYERS 'ATTORNEY United States Patent 2,770,991 SPANNER WRENCH FOR CALKS Robert E. Myers, Bangkok, Thailand Application May 2, 1955, Serial No. 505,418

3 Claims. (Cl. 81-90) This invention relates to new calk means. In a more specific aspect, this .invention relates to new calk means I by athletes and in sports such as golf, the calks being threadedly mounted for easy replacement of broken or worn calks or for the repair of the shoe proper. Also, calk seating and unseating spanner wrenches have long been known in the art, such utilizing spaced cylindrical pins corresponding to spaced round holes in the calk body which upon turning the wrench contact the calk body to turn same and seat or unseat the calk. These wrench means are very inconvenient to use, it being difiicult to keep the wrench pins in the calk holes, and in using the wrench .it must be removed and reinserted after each 90 to 180 degree turn. This is necessary because the wrench will not stay locked in turning position with the calk but falls out of turning relation therewith. Improved threadedly mounted calk means and seating and unseating means therefor have long been needed in the art, and I have invented just such means which has/been found to overcome the difficulties encountered with the known calk and wrench means.

I have invented new calk means which has openings therein to receive wrench dogs which have transverse portions, so that the calk means is turned when the dogs are in the openings, and so that the dogs turn into locked position with the calk, when the wrench is turned to operate same. The new Wrench means of my invention has a shank portion with means therewith to turn the shank and a head portion on one end portion of the shank. Dog members are mounted on the head portion of the wrench, and these dog members have transverse portions spaced from the head portion. These transverse dog portions fit into the openings in the calk means.

The new calk and wrench means of my invention has been found to overcome the difficulties encountered with the round hole calk and cylindrical pin calk wrench. The new wrench means of my invention remains in locked relation with the calk means so that the users hand can be completely removed from the wrench to regrip same for further turning. In a preferred specific embodiment of my new calk wrench means, the operating dogs are made interchangeable and removable for replacement and each end portion of the dogs are usable upon reversing them. The new means of my invention is easy and economical to manufacture, and convenient to use.

It is an object of this invention to provide new calk means.

It is another object of this invention to provide new calk means and wrench means therefor.

Yet another object of this invention is to provide new calk wrench means for seating or unseating calks which are threadedly mounted on the soles and/or heels of shoes.

Other objects and advantages of my invention will become apparent to those ski'lled in the art upon reading this disclosure.

Drawings accompany and are a part of this disclosure. These drawings depict preferred specific embodiments of the new calk and wrench means of my invention, and it is to be understood that such are not to unduly limit the scope of my invention.

In the drawings,

Fig. 1 is an exploded perspective view of a preferred specific embodiment of the new calk wrench means of my invention.

Fig. 2 is an elevation view partly cut away and partly in cross section showing the wrench of Pig. 1 in operating relationship to a preferred specific embodiment of the new threadedly mounted calk of my invention.

Fig. 3 is a top plan view of the new calk means of my invention shown in Fig. 2.

Fig. 4 is an enlarged perspective view of the new spanner dog of my invention used in the wrench of Figs. 1 and 2, such enlargement showing in detail a particularly preferred shape of dog.

Fig. 5 is an elevation view partly in cross section of another preferred specific embodiment of the new spanner wrench means of my invention, such being without replaceable dog means.

Following is a discussion and description of preferred specific embodiments of my invent-ion made with reference to the drawings whereon the same reference numerals are used to indicate the same or similar parts or structure, and it is to be understood that such discussion and description is not to unduly limit the scope of my invention.

The calk wrench of Figs. 1, 2 and 4 has a spindle 7 on which turning handle 9 is mounted in any suitable manner such as by welding. Handle 9 has a pointed end portion 11 which can con veniently be used to clean caked mud or dirt from shoes and calk s, or for similar purposes, as desired. The other end of handle 9 conveniently has a recess 13 which can be used to store extra or spare Wrench dogs described hereinafter, and a removablecap 15 is threadedly secured in the end of handle 9 to retain the spare dogs therein.

Spindle 7 has an integral enlarged cylindrical head portion 17 on the end opposite the handle end, and such can be a separate head mounted on spindle 7 in any suitable manner such as by welding, if desired. Head 17 has a pair of diametrically opposite grooves 19 therein parallel to the longitudinal axis of spindle 7, and these can be formed therein by the usual and common machining methods.

The wrench has a pair of I-shaped dog members 21 which are mounted one in each of grooves 19 with the upright portion 23 thereof mounted in the grooves. The transverse end portions 25 of dogs 21 rest, while dogs 21 are in the grooves, with the inner end in contact with head 17 and the outer transverse end 25 spaced from head 17. These transverse end portion 25 are preferably arcuate on the outer face and tapered in the outer end portions as best shown in Fig. 4 so that they snugly fit in the wrench and so that the end portions will easily slip under a calk body for operation as set forth hereinafter. The dogs are interchangeable and either end can be used which has been found to be of very great advantage.

The dogs 21 are retained in grooves 19 by sleeve 27 which is preferably threadedly secured to spindle 7 as shown, so that the sleeve around head 17 can be removed to reverse or replace dogs 21. Sleeve 27 is preferably 3 threaded opposite to the calk means or made to fit slightly short of the end of head 17 so that the sleeve will not be loosened when the wrench is operated.

Fig. 2 shows the wrench means in operating position and assembly, in a position to seat orunseat the new calk means of my invention. The calk has a convexoconcave body 29 which is more concave than the usual and common calk so that there is room for end portions 25 of dogs 21 to fit thereunder between the calk, body 29 and bushing 31 which is mounted in shoe sole 33. The calk has a centrally located root member 35 which is threaded to mount the calk in bushing 31. A centrally located tapered spike 37 projects outwardly from the base member 29 and is the ground engaging member toprevent slipping. Body member 29 has two diametrically opposite holes 39 therein to receive transverse end portions 25 of dogs 21 as shown in Fig. 2. The end portions of ends 25 slip under body 29 when spindle 7 is turned, locking the wrench and calk together so that the hand can be removed from the wrench for another grip without the wrench being removed from the calk. Normally, the golf shoe (not shown) having sole 33 is held in one hand and the wrench in the other and as one skilled in the art can see, a person with my wrench can seat or unseat a call; much faster and efiiciently than with the usual spanner wrench using projecting pins, with no interlocking structure between the calk and wrench.

In Fig. 5 is shown another specific embodiment of my invention wherein the head portion 41 on spindle 7 has the dog members spaced thereon and projecting therefrom. This wrench lacks the interchangeable and reversible dog features of my other depicted embodiment, but it will conveniently seat or unseat the new calk means of my invention in the same manner as my more versatile wrench embodiment.

The new means of my invention can be made of any suitable material and in the usual and common methods of manufacture. I prefer that they be made of metal, strong aluminum alloys, steel, and the like being preferable. The dog means 21 isdesirably made of steel.

As will be evident to those skilled in the art, various modifications of my invention can be made, or followed, in the light of this disclosure and discussion, without departing from the spirit or'scope of the disclosure, or the scope of the claims.
